-**Notes (delete this)**
-Github Discussions (https://github.com/zephyrproject-rtos/zephyr/discussions)
-are available to first verify that the issue is a genuine Zephyr bug and not a
-consequence of Zephyr services misuse.
-
-This issue list is only for bugs in the main Zephyr code base
-(https://github.com/zephyrproject-rtos/zephyr/). If the bug is for a project
-fork (such as NCS) specific feature, please open an issue in the fork project
-instead.
-
-**Describe the bug**
-A clear and concise description of what the bug is.
-
-Please also mention any information which could help others to understand
-the problem you're facing:
- - What target platform are you using?
- - What have you tried to diagnose or workaround this issue?
- - Is this a regression? If yes, have you been able to "git bisect" it to a
-   specific commit?
- - ...
-
-**To Reproduce**
-Steps to reproduce the behavior:
-1. mkdir build; cd build
-2. cmake -DBOARD=board\_xyz
-3. make
-4. See error
-
-**Expected behavior**
-A clear and concise description of what you expected to happen.
-
-**Impact**
-What impact does this issue have on your progress (e.g., annoyance, showstopper)
-
-**Logs and console output**
-If applicable, add console logs or other types of debug information
-e.g Wireshark capture or Logic analyzer capture (upload in zip archive).
-copy-and-paste text and put a code fence (\`\`\`) before and after, to help
-explain the issue. (if unable to obtain text log, add a screenshot)
-
-**Environment (please complete the following information):**
- - OS: (e.g. Linux, MacOS, Windows)
- - Toolchain (e.g Zephyr SDK, ...)
- - Commit SHA or Version used
-

-# Background
-
-The [TSC Project Roles] defines the main roles for the Zephyr Project, including
-Maintainer, Collaborator, and Contributor.
-
-By default anyone that contributes code or documentation is a Contributor, but
-with the lowest [GitHub Permission Level] of Read. For example, Contributors
-with Read permission do not have the permission to add reviewers to a pull
-request.
-
-Use this template to nominate a GitHub user for the Contributor role with
-Triage permission level, which allows the user to add reviewers to a pull
-request and be added as a reviewer by other users.
-
-# Nomination
-
-## GitHub User
-
-Provide the following information about the GitHub user:
-
-1. Full Name
-1. GitHub username
-1. Organization (optional)
-
-## Supporting Documents
-
-Add links to 3-5 GitHub pull requests, in the Zephyr project, authored or
-reviewed by the GitHub user that demonstrate the user's dedication to the
-Zephyr project.

+## Our Responsibilities
 
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
+Project maintainers are responsible for clarifying the standards of acceptable

+response to any instances of unacceptable behavior.
 
-Community leaders have the right and responsibility to remove, edit, or reject

 ## Scope
 
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
 
 ## Enforcement
 
 Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-conduct@zephyrproject.org. Reports will be received by the Chair of the Zephyr
-Governing Board, the Zephyr Project Director (Linux Foundation), and the Zephyr
-Project Developer Advocate (Linux Foundation). You may refer to the [Governing
-Board](https://zephyrproject.org/governing-board/) and [Linux Foundation
-Staff](https://zephyrproject.org/staff/) web pages to identify who are the
-individuals currently holding these positions.
-All complaints will be reviewed and investigated promptly and fairly.
+reported by contacting the project team at conduct@zephyrproject.org.
+Reports will be received by Kate Stewart (Linux Foundation) and Amy Occhialino
+(Intel). All complaints will be reviewed and investigated, and will result in a
+response that is deemed necessary and appropriate to the circumstances. The
+project team is obligated to maintain confidentiality with regard to the
+reporter of an incident.  Further details of specific enforcement policies may
+be posted separately.
 
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
